What are S32750 Pipes & Tubes?

S32750 stands out due to its carefully engineered metallurgy. This Super Duplex grade features high chromium (~25%), molybdenum (~4%), and nitrogen (~0.27%), balanced with nickel (~7%). This chemistry creates an optimized 'duplex' microstructure (roughly equal austenite and ferrite phases), which is key to its performance:

• Outstanding Corrosion Resistance: High Cr, Mo, and N provide exceptional defense against pitting and crevice corrosion, vital in chloride-rich environments (e.g., seawater). Its Pitting Resistance Equivalent Number (PREN) typically exceeds 40, indicating superior performance over standard duplex and many austenitic grades. It also boasts excellent resistance to general corrosion and Chloride Stress Corrosion Cracking (CSCC).
• High Mechanical Strength: S32750 offers significantly higher yield and tensile strength than common austenitic grades (like 316L) and standard duplex steels. This allows for thinner wall designs, leading to weight savings and potential cost benefits in structural or high-pressure applications.
• Good Weldability & Toughness: While requiring controlled procedures, S32750 welds well. Proper techniques ensure welds retain excellent toughness and corrosion resistance. It also maintains good impact strength at moderately low temperatures.

These properties make S32750 Alloy Pipes and 2507 Duplex Steel Tubing ideal for critical applications demanding both strength and elite corrosion control.
